FOUNTAIN-PEN.

sPncIFIcATIoN forming part of Letters'ratent No. 734,563, dated .my 2e,1903. Appncation med'ntmber 9,1902. serial No. 134,514. (No maar tainnew and useful Fountain-Pen, of which' the following is a specification,reference be-A ing had therein to the accompanying drawings.

This invention relates to fountain-pens,the

principal object of the invention being to pro- Avide a pen of the classreferred to which is always ready for use and which may be reversed orused either side up, the ink being supplied simultaneously to both sidesof the pen-point, provision being also made at the same time whereby airis admitted to the penreservoir at either or both sides of the penpointto insure the proper flow of ink.

A further object of the invention is to construct the pen holder orclamp in such man# ner that the proper positioning of the penpointtherein will be insured, the placing of the holder or clamp in the bodyof the pen made easier and more reliable, and the cost of the pen as awhole reduced to aminimum.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination, and arrangement of parts,as hereinafterfully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a central longitudinal sectionthrough a fountain-pen constructed in accordance with this invention,said view being taken at right angles to the plane of the pen-point.Fig. 2 is a similar section taken at right angles to Fig. l and omittingone of the pen holder or clamp sections. Fig. 3 is an enlargedcross-section taken through the end portion of the pen.'

Fig. 4 is a detail longitudinal section through the pen holder or clampsections. Fig. 5 is a plan view of one of the peu holder or clampsections. Fig. 6 is a plan view of the penpoint. Figs. 7 and Slare edgeviews of the pen-point, Fig. 8 illustrating a slight modili` cation ofthe construction shown in Fig. 7.

Like reference-numerals designate corresponding parts in all the figuresof the draw- 1ngs.

Referring to the drawings, the pen is seen to comprise the usualbarrel-shaped body or `reservoir l, ,havinga tapering end portion 2,

which is made removable from the main bodyI or re)servoir byascrew-thread joint, (shown at 3.

In carrying out the present invention the Vbore 4 of the end portion 2is enlarged or made, flaring outwardly, as shown at 5, adjacent to theextremity of said end portion` in order to adapt it to receive with awedging fit the ta-V pering inner portion of the peu holder yor clamp 6.

The pen holder or clamp 6 is preferably composed of twin sections 7,which taper reversely from about the center in opposite directions, asbest illustrated in Figs. l and 4, the taper of the inner portions ofthe sections corresponding with the flare of the outer portion of thebore 4, so that when the sections lare pushed into the end of the bodythey will be held frictionally after the manner of a lwedge and will atthe Asame time securely clamp the pen-point 8 between them.

In order to receive and hold the pen-point 8, the parts 7 of the penholder orclamp are recessed, as shown at 9, to provide a space equal tothe thickness of the pen-point, shouli ders or stops 10 being at thesame time formed at the rear ends of the sections 7 to limit thebackward movement or insertion of the penpoint, thus permitting the.proper amount of the pen-point to project beyond the outer end of theholder or clamp.

Each section 7 is also 'provided interiorly with a longitudinal groove11, which forms the ink-duct, the latter extending from the inner end ofthe holder or clamp nearly to the outer extremity thereof, as shown inFigs. l and 4. Each section is further provided exteriorly with arelatively small groove 12, which forms the air-duct, said grooveextending from the inner end of the holder or clamp to a point slightlybeyond the center, or, more accurately speaking, beyond the end of thebody of the pen when the holder or clamp is in its inserted position,thus permitting air to pass into the reservoir to take the 'place of theink iiowingtherefrom.

nThe pen-point 8 is perfectly flat, being roo clamped or otherwise cutfrom sheet metal of the requisite thickness. The pen-point is preferablyprovided with an ink-holding recess 13, While the point or nib may beenlarged or thickened, as shown at 14 in Fig. Y8, or left the samethickness of the body of the pen-point, as shown in Fig. 7.

From the foregoing description it will be understood that ink issupplied automatically to both sides of the pen-point and that air mayenter the reservoir also at both sides of the pen-point. Therefore itmatters not which side of the pen-point is used in writing, thusenabling the device to be used either side up. This feature is ofspecial value to rapid writers, who are compelled to frequently lay downand take up the pen. It Will also be observed that the pen is extremelysimple to repair and clean, it only being necessary to apply suicientpulling force to the sectional holder or clamp to Withdraw the same fromthe end portion of the body or reservoir, whereupon the sections of theholder and the pen-point maybe disassociated. In reassembling the partsthe pen-point is inserted between the sections of the holder or clampuntil its rear end abn ts against the shoulders l0. The holder or clampas a whole is then, together with the penpoint, inserted in the body orreservoir and pressed inward with sufficient force to enable the holderto beheld Within the daring part of the end portion of the bodyfrictionally or with a wedging fit. The holder or clamp sections arethus caused to bind against the pen -point on opposite sides andsecurely hold the latter in proper position. A l

Having thus described the invention, what is claimed as new, and desiredto be secu red by Letters Patent, is-

l. A fountain-pen comprising a body, a sectional pen holder or clampseated with a wedging fit in the end of the body, and a penpoint heldbetween the sections of the holder or clamp.

2. A fountain-pen com prisinga body, a sectional pen holder or clamphaving a tapering rear end portion seated with a wed'ging fit in the endof the body, and a pen-point held between the sections of the holder orclamp.

3. A fountain-pen comprising a body having a tapering andoutwardly-flaring seat, a sectional pen holder or clamp having atapering rear portion held with a wedging it in the tapering seat, and apen-point held between the sections of the holder or clamp.

et. A fountain-pen comprising a body, a sectional pen holder or clampseated with a wedging iit in the en d of the body and provided Withoppositely-located ink-ducts, and also having a pen-point recessterminating at the rear in a shoulder, and a pen-point held between thesections of the holder or clamp.

5. A fountain-pen comprising a body hav ing a tapering andoutwardly-Haring seat, a pen holder or clamp consisting of sections theinner portions of which are tapered adapting them to be inserted with aWedging t in the tapering seat, each section being provided with ink andair ducts, a pen-point held between the sections of the holder or clamp,and oppositely-located shoulders on said sections for limiting theinsertion of the pen-point.

6. In a fountain-pen, a holder or clamp for the pen-point having meansfor conducting ink simultaneously to both sides of the .penpoint andalso means for admitting air at both sides of the pen-point.

7. In a fountain-pen, a fiat pen-point, in combination with a pen holderor clamp constructed to supply ink to both sides of the pen-point andalso to admit air at both sides ot' the pen-point whereby the pen-pointmay be used either side up, substantially as described.

In testimony Whereof I aiix my signature in presence of two witnesses.
